Defaults follow the Factories Act, 1948: overtime after 9 hours a day or 48 hours a week, paid at twice the ordinary rate. Shops and offices follow their state's Shops and Establishments Act, which may differ.

What is a time card?

A time card records when you start and finish work each day, with breaks, so that hours and overtime can be paid correctly. This calculator adds up a week, finds overtime and works out pay. By default it follows the Factories Act, 1948: no more than 9 hours a day or 48 a week, with overtime paid at twice the ordinary rate. You can change the limits and rate to match your employer or state rules.

Hours and overtime

Daily hours = out − in − break · Overtime = larger of (Σ hours above the daily limit) and (weekly hours above the weekly limit) · Pay = normal hours × rate + overtime × rate × 2

Overtime is counted once even when both the daily and weekly limits are crossed: the larger of the two excesses is used.

Good to know

  • Under the Factories Act, adult workers shouldn't work more than 9 hours a day or 48 a week, with a rest interval of at least 30 minutes after 5 hours.
  • Overtime is paid at twice the ordinary rate of wages, which under the Act includes basic wages and allowances.
  • Shops, offices and IT companies are covered by state Shops and Establishments Acts, whose limits differ. Many salaried staff aren't paid overtime at all.
  • The spread-over of a working day, including breaks, shouldn't exceed 10½ hours under the Factories Act.
  • Keep a copy of your time records. They're the main evidence in any dispute about unpaid hours.

Worked example: a 6-day week

  1. Monday to Friday 09:30–18:30 with a 60-minute break: 8 hours a day
  2. Wednesday runs late, to 20:30: 10 hours, 1 above the 9-hour limit
  3. Saturday 09:30–14:30 with no break: 5 hours
  4. Week: 8 × 4 + 10 + 5 = 47 hours, under 48, so overtime is the 1 daily excess hour
  5. At ₹200 an hour: 46 × ₹200 = ₹9,200 plus 1 × ₹400 = ₹400, total ₹9,600

Subtract the start time from the end time and then the break. 09:30 to 18:30 with a 60-minute break is 8 hours.
Usually not. Rest intervals are excluded, which is why the calculator subtracts them.
Enter the times as they are, such as 22:00 to 06:00. An out time earlier than the in time is taken as the next day.
